Optional Features

Some of these features require CGI scripts to execute on your server. In order for them to function, make sure your server is configured to allow the execution of CGI files. Next, enable these features in your configuration file.

Layer Preview Images

By default during the build process we try to fetch images of layers from our Snapshots application to show as previews in the layer picker component. However, this will only work for layers that are present in NASA GIBS (Global Imagery Browse Service). If you are serving your own layers, you will likely wish to disable this feature by setting "previewSnapshots": false in config/default/common/features.json.

Natural Events

This feature provides natural events queried by Earth Observatory Natural Event Tracker (EONET) by default. To enable, edit config/default/common/features.json and set:

"naturalEvents": {
    "host": "[host_url_here]"
}

to disable, set: "naturalEvents": false

Data Download

This feature uses CGI scripts to query the CMR API on the server. To enable, edit config/default/common/features.json and set "dataDownload": true.

URL Shortening

This feature uses bit.ly to shorten links. Follow these steps to enable it:

  • Edit config/default/common/features.json and set "urlShortening": true.
  • Get a login and API key from bit.ly.
  • Create build/options/bitly.json with the following contents (replacing your_login and your_key with the appropriate values);
{
  "login": "your_login",
  "key": "your_key"
}

Caution: Do not commit this file to a public repo, and make sure the build/options directory is not publicly accessible on your web server to protect the privacy of your API key.
